History this map
In 1791 the Board of Ordnance established a body to survey
Britain; the first 1-inch map, which showed Kent, was produced
in 1801. The other counties of the United Kingdom followed.
Surveying involved the laborious measuring and mapping of a
myriad topographical features, including hills, roads, field
boundaries, houses and woods.
These special first-edition maps were updated as the Victorian
age progressed; new roads and railways were added, and major
new buildings such as factories, gas and water works marked.
It is from these enhanced 6-inch maps that the Frith Ordnance
Survey maps have been created.
